In BW/4HANA SAP offers you the possiblity to link restricted or calculated keyfigures accross different Composite Providers. The advantage of the link components concept is that they can automatically synchronized whenever you make changes in the source or master component. If you are not familiar with this concept.
"A linked component can be automatically synchronized whenever changes are made to the corresponding source component.
Example scenario: You have two highly similar InfoProviders, IP_A and IP_B. You have created the query Q_A for IP_A. You now want to create the query Q_B for InfoProvider IP_B. You want this query to be very similar to query Q_A and to be automatically adjusted whenever changes are made to query Q_A.
To do this, you use the link component concept: You create the linked target query Q_B for source query Q_A. This is more than just a copy, as the system also retains the mapping information. This mapping information makes it possible to synchronize the queries."
Last week a collegue and I look into the XXL InfoObjects in SAP BW/4HANA. We searched the online help and there is a short video about the topic. But after that we had no clue how we can use it. Can we use it in Analysis for Office? Or just in the query or Composite Provider? What is the purpose of these InfoObjects? Can we store a documentation and open it directly from the query?
At the end of last month I ask on Twitter why I should create a join between an Advanced DataStoreObject and an InfoObject to read the attributes from this InfoObject when I even can activate the attributes on the output tab of the Composite Provider in SAP BW/4HANA. The answers on twitter was not satisfactory and I ask a collegue if he knew a reason. So i build a Composite Provider with a join between an InfoObject and an ADSO in our BW/4HANA system.
Open ODS are a long time available in SAP NetWeaver BW. You can access directly database tables, database views or BW/4HANA DataSources (for direct access). In this blog post I want to look into the fast and agile modeling with Open ODS Views. So we start with a flat file we for example received from our customer to build a new data flow for reporting. The file has the following strucutre:
I lately looked deeper into the modeling of Composite Provider in BW/4HANA 2.0 and found some difference between a BW/4HANA 1.0, BWonHANA 7.50 and the latest version BW/4HANA 2.0. So let's compare them and see what's new and we can go deeper in further posts. We start with the context menu of the scenario for the provider.
You have different ways to store the logic of your customer exit variables in SAP BW/4HANA. After my last post about Customer Exit Variables with an own enhancement spot I want to share another solution with you. In this blog post I want to show you how you can implement a BAdI implementation with a Z-Table (Customer Table). In this table you find the assignment between the BEx variable and the corresponding class for the customer exit. This is how the table will look like:
For a long time we used for checking and manipulation of customer exit variables the enhancement RSR00001. Since SAP BW 7.3 SAP offers the BAdI RSROA_VARIABLES_EXIT_BADI. Since BW/4 you only could use this BAdI and not anymore the enhancement RSR00001.
The BAdI RSROA_VARIABLES_EXIT_BADI is a filter based BAdI. As filter object is used the InfoObject which the variable is based on. Every implementation calls the interface IF_RSROA_VARIABLES_EXIT_BADI~PROCESS. So now let's create an example customer exit variable. The variable is based on Sales Channel (ZQV_ZSALCH_CEO_001) and can handle multiple single values.
I recently got a BW/4HANA 2.0 project. So I want to share some ideas and thoughts I discover in the whole process. First things first. Everything and I mean everything is only available in the BW/4 cockpit now. ADSO, InfoObject, Hierarchy management and even the Process Chain management is only available in the web. Some things are very confusing when you see it first. But let's dive in.
In our current project we had to deal with the requirement that the enduser only want to show a certain node of a hierarchy to filter. So we used the F4 restriction from the transaction spro. You find the entry under Business Warehouse >> Enhancements >> BAdI: Restricting the Value Help in the Variables Screen. We implemented it in the method GET_RESTRICTION_NODE.
At this time I had only experience with the method GET_RESTRICTION_FLAT and searched for implementation examples. I found a wiki entry on scn. In our case we had bookable nodes so we implemented it like this to get these node and all children of it.
l_s_node-nodename = 'NODE1'.
l_s_node-niobnjm = 'ZZ_IO'.
Append l_s_node to c_t_node.
But it didn't work out. The debugging showed no error, but the restriction always showed the complete hierarchy. After a little digging we found our mistake, it have to look like the follwing:
l_s_node-nodename = 'LEAF1'.
Append l_s_node to c_t_node.
l_s_node-nodename = 'LEAF2'.
Append l_s_node to c_t_node.
And so on for all leafs. So we had to add all leafs and not the nodes. I didn't found any good explanation so here is the short article about it. Thanks to my collegue who had the problem.
Here just a short notice if somebody doesn't know it yet. If you have a false information in a data record you can fix this manually either in a PSA or (A)DSO. Just select the desired entry and click Display (F7).
In my current project we have the hide a position in a hierarchy, because it is a departmental requirement. The hierarchy is used by many departments so we cannot change it and we also don't want to have the same hierarchy two times (except for the one position). So we first excluded the position in the query.
In my current project I have to filter data with a lot of logic. So I build some ABAP routines in a DTP filter to receive the necessary data. First you have to open the DataTransferProcess (DTP) in change mode and select the Filter button on the Extraction tab.
In my current project we have a go live. So I needed a function to reset the transport status of some transports. So if you release your transport falsely the transport is locked by release and can no longer be removed from the transport status. Maybe you also want to delete the entire transport request. This option is also denied as soon as the tasks have been released. The standard procedures are very laborious and not only cost a lot of time, but also have a certain risk potential. SAP offers a report which solves your problem. The report is RDDIT076. As you see in the next picture, the transport is released.
A new function in Analysis Office 2.7 is "Select Data Source for Defining Formulas". But what does this mean? First the prerequisites:
So I just logged into my BW 7.50 test system and what I have to see, we only have a BW 7.5 SP11. So I have applied the notes and each note need further notes to implemented. I just want to test something and now I have to implement more than 30 notes.
In my current project we run into an issue that we have to match navigation attributes from one ADSO to an infoobject of another ADSO. The old feature of a MultiProvider was to Identify (assign).
I hope you can help me, to find out if there is any interesting about a book that covers BW Backend topics. I think about a book which covers SAP HANA, AMDP/ABAP, BW Administration and so on. Thanks for your time.
In my current project I have a file to import, which only delivers me a string with a length of 1000. I also get a description what is in this file. Like the following points:
The file looks like: 0000123456London............................ So I have a file and a description how to decode this file. Now I need to find a way to separate this information into InfoObjects. I build a Z-Table which contains the decode information.
Lately, all my posts started with "In my current project", so now something else, even if it was developed in the current project. The problem we are facing with is that we get a data extraction which deliver us only the new data records, not the reverse data record.
In my current project we have a lots of source systems which delivers our data in a key figure model. In a normal case is this not a problem. But we need the values of the key figures in a hierarchy. So there are two ways to realize it. First way would be we build a structure with restricted key figures and get our hierarchy. Here is the problem, the customer will need different queries to realize his needs. If there is a change, we need to adjust different queries (each has a light different hierarchy) and the maintainace is immense.
In my current project I created with a collegue a really cool function to analyze a string with 1333 characters. We are using a BW 7.4 SP 17 on HANA. First we have to build an Advanced DataStoreObject with a Field which has a length of 1333. For further understanding, we call the field Field_1333. As data type I used SSTRING.
I know that I don't publish a lot of new posts the last few weeks. The reason is I am writing on my diploma thesis. The title is "S/4HANA versus BW/4HANA - Zukunft der Datenanalyse". My deadline is in the middle of September so I have to write a lot these days. At the moment, I have access to a BW/4HANA instance in the cloud and I want to share how you could export your development before you terminate the instance. First you have to log on with the SAP* user in the client 000. Go to the transaction stms and select the System Overview.
I described in a earlier post how to use BW/4HANA on Amazon AWS. But if you just need a developing system for some time and don't want to use BW/4HANA, you can use the BW 7.5 SP2 developer edition on a virtual machine.
I want to document a BW data model and searched for a Microsoft Visio shape, but I found nothing. So I build my own Visio shapes. At the moment there are the following types available:
I used them in my last blogpost about Copy Queries to a new MultiProvider.
In my current project, we want to separate the current MultiProvider with VirtualProvider underneath into one MultiProvider with VirtualProvider and one MultiProvider without VirtualProvider. This step is necessary, because we receive a lot of data and don't want to push all these data through the VirtualProvider. The VirtualProvider only add one field which we haven't got in our InfoCubes and it isn't necessary in all queries just a few.
At the moment I had to deal with a special problem. I have data in a SPO from two different sources and the goal was to find the corresponding two data lines and make one out of it. This line should marked with a special character. So I decided to build an Analysis Process (APD).
Sometimes it is necessary to check your data model if it still fit your needs. For this you can use the transaction rsrv. Select there under All Elementary Tests >> Database >> Database information about InfoProvider tables.
In my current project I had to clean up the existing process chains. A lot of process chains were created via SPOs and not really used in the system. First I had to check, if one is used in a another process chain or in which one they are used.
In my current project we have to transport from a maintenance system to our development system. The problem is when you now transport the objects into quality system, you have to check the option "Overwrite Originals" so that your transport is working. But you have to put this flag on every transport you make in the future from your development system to quality.
In my current project, we have a copy of the productive system as a maintenance system, because we made huge changes in
the development system in case of the project. So if there is an error in the production, we can easily repair it.
Some changes have also be transported into the development system, so we have the same state and our future request can be transported into production. For this we use the functionality Transport of Copies. All objects of the originally request are still locked. If you want to create a transport of copies, open the transaction SE01. Check the option “Transport of Copies” and click on Display.
After we created in Part 1 the transparent tables and in Part 2 all BAdI implementation, we can now maintain and create our SPO. First we have to fill our table ZSPOPATTERN with a PATTERNID and a corresponding INFOOBJECT. Go to the se16 and create a new table entry. As PATTERNID enter a unique id for example CALYEAR and as INFOOBJECT 0CALYEAR. For TXTLG and TXTSM enter a useful text. Depending on how many InfoObject are used for a partition, create the other pattern.
After we created in part 1 all tables and objects, we can now create a new BAdI to generate the partitions. Go to the transaction se19 and create a new implementation with the Name RSLPO_BADI_PARTITIONING.
At my current project I needed a way to create Semantic Partitioning Object (SPO) via BAdI to reduce the end-of-year work. After a little search via Google (you cannot find anything on the new SAP Community Page), I found these threads.
So after I read a lot about BW/4HANA, I decided to create a own SAP BW/4HANA 1.0 [Developer Edition] instance on my Amazon AWS account. First I had to extend my normal AWS account with a IAM user. For this you choose under Security, Identity & Compliance >> IAM. Under Users you click on Add user.
So it is done, Part 2 finally is written and an example is uploaded to github. It took me about 8 months to release Part 2 of these series. Part 1 was released in March 2016 and now I had time to write an example for Part 2 and upload it to github. Part 1 discover the basics about a RFC Server with the SAP NCo Connector, part 2 now explain how to build a RFC Server more flexible.
This week the new open SAP course BW/4HANA in a Nutshell started. It is a free course. One big thing is that BW/4HANA no longer supports the good old BEx Suite. You now have to use the BW Modeling Tools based on Eclipse. In this and further posts I will go deeper into the BW Modeling Tools and what is possible and what is not possible at the moment.
If you have any questions feel free to ask or correct me ;) So let's get started.
I just got access to a NetWeaver 7.5 SP2 and I want to test it with Analysis for Office 2.3. So I open Excel and insert a query. And here we go first error: "unable to open data source", so I thought maybe the query is broken and I developed a new query and insert it. Here we go, same error. Maybe queries don't work, so I insert a InfoCube directly. Same error...
Now I refresh the insert query and got an Analysis for Office message: Error while executing function module: BICS_PROV_OPEN
In the explanation was one line with the hint "wrong parameter type in an rfc call", so I looked into st22 and saw a dump which the message: CALL_FUNCTION_ILLEGAL_P_TYPE
In some cases you want to trigger an external program from a SAP system. In this part 1 I explain how to build a RFC Server with NCo 3.0. I had several problems when I started with this topic so I decided to write a short example. If someone want the Visual Studio project files, please contact me.
So let's go.
This Post describes how to build a simple RFC Server using SAP NCo 3.0 and the app.config. Part 2 will be describe how to build a RFC Server with RFC Parameter. As example program I use STFC_CONNECTION. It is a good example, because it contains importing and exporting parameters.
First you have to download and install NCo 3.0 (OSS login required). Afterwards you have to start a new project in Visual Studio.
Setting up the Visual Studio Project:
In the properties of the project you have to use a new console application. As target framework I use .Net Framework 4.5.
In the last time I had several problems with external access to a SAP BW System. The access was realized with an old version of the SAP Connector. And that is the problem. If you have a SAP Business Warehouse System version which is greater than 7.3, you maybe get troubles. For example SAP added new fields or like in 7.4 you now have the option for "Long text is XL" in the master data. So the old versions would not work with this.
I just found a very good table about the maintenance of all versions in Martins blog.
If you want to delete or rename an Analysis for Office Workbook, you have to right click on the Workbook Opendialog.
After „SAP BW 7.4 Maintain characteristics“ is one of the most read posts. I visualize this post in a short video.
In BEx Analyzer you could jump into another query from a query / workbook. The GoTo-Function make sense if you have one query for overview and one for detail.
You can use the ABAP program RRMX_WORKBOOKS_GARBAGE_COLLECT to find workbooks that are currently assigned to a user or group of users via the transaction SE38. Through the hook "Workbooks found erase" these are removed from the system.
With every new release of SAP HANA functions are moved from the OLAP engine into the database. The current state of the push down can be found in note 2063449. So check this note from time to time, if it is interesting to implement a service pack.
Note: You need a S-User to access this note.
Unfortunately, SAP shifted the maintenance of master data in SAP BW 7.4 into the Web. Not everyone wants to maintain the master data on the Web. Here is a small workaround.
From time to time there is a mistake in the resolution of structured items and the transfer of material hierarchies to BW. It helps the Note 1410263.
From time to time it happens that the source system delivers special characters and the Business Warehouse system can not handle it. So the loading process may be crashed.
One solution is the following ABAP code:
SAP BusinessObjects Web Intelligence
There is a SAP Note which was released 2009. This Note shows how to change key figures of an InfoProvider, even though they are used. The Note is 579342.
When the BEx Query Designer crashes while you are creating or modify a query, the user lock this query in the database. You can remove the lock with the Transaction sm12 and erase the entry.
From time to time it is necessary to replicate DataSources from other SAP systems, eg if the DataSource has changed in the source system. To replicate a DataSource, use the transaction rsa1.
Now the DataSource can be used.
Query to Read All Data at Once
Query to Read Data During Navigation
Query to Read When You Navigate or Expaned Hierarchies
If you have created your own SAP function module, you can use this with the following VBA code.
Dim MyFunc As Object
Dim E_INSERTED As Object
Dim E_MODIFIED As Object
Dim DATA As Object
Set MyFunc = R3.Add("Z_RSDRI_UPDATE_LCP") 'FunctionModule Name in SAP BW
Set E_INSERTED = MyFunc.imports("E_INSERTED") 'InsertFunction in SAP BW
Set E_MODIFIED = MyFunc.imports("E_MODIFIED") 'ModifyFunction in SAP BW
Set DATA = MyFunc.tables("I_T_DATA") 'Table to store data and write to BW.
DATA.Rows.Add 'add new data
rowDATA.Value(1, 1) = Sheet1.Cells(1, 10).Value 'First Cell of the data table is filled with the value from Sheet1.Cells(1,10)
'Call Insert or Modify
Result = MyFunc.CALL
'Message to the User
If Result = True Then
MsgBox "Insert Rows: " & E_INSERTED.Value & " Modify Rows: " & E_MODIFIED.Value, vbInformation
MsgBox MyFunc.EXCEPTION 'Exception
Sometimes you want to know which users are created on a Business Warehouse system and if these have access or have been blocked from by incorrect logon. For this you can use the transaction rsusr200. In the transaction you can see the last login, the users validity, etc.
Sometimes you have to check the rights of users. For this you can use the transaction su53.
If you adjusts many objects in the Business Warehouse, a lot of transformations are automatically inactive. So you don't have to activate each transformation by hand, there is a ABAP program named RSDG_TRFN_ACTIVATE.
There are several ways to look at the structure of an InfoCube. One way possibility would be to analyze it on the transaction rsa1. Another way to show the structure of an InfoCube is the transaction listschema.
If you want to create automated reports with data from an SAP ERP or Business Warehouse system, you first need to connect to a SAP system. The connection can be used later to access system tables in the ERP or Business Warehouse or to trigger various other action.
